Answer:
[tex]6.7\ units[/tex]
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
(4,2) and (7,8)
substitute the values in the formula
[tex]d=\sqrt{(8-2)^{2}+(7-4)^{2}}[/tex]
[tex]d=\sqrt{(6)^{2}+(3)^{2}}[/tex]
[tex]d=\sqrt{45}\ units[/tex]
[tex]d=6.7\ units[/tex]
